In relation to septic systems, what role does a "grease interceptor" serve?

A grease interceptor serves a very specific function in the management of wastewater generated by food service establishments. Its primary role is to separate fats, oils, and grease from sewage before this wastewater enters the septic system. This separation is crucial because fats, oils, and grease can solidify and create blockages in the plumbing and septic systems, leading to potential system failures and costly repairs.

By removing these substances from the wastewater stream, the grease interceptor helps maintain the integrity and efficiency of the septic system. It allows for the more effective treatment of the remaining wastewater by the septic tank, promoting a healthier environment and reducing the risk of environmental contamination. This separation process ensures that only liquids and dissolved solids enter the septic system, thus supporting its long-term functionality.
